Objective To investigate the effects of chronic renal failure rabbit serum on proliferation and nuclear factor kappa B (NF-κB) activation of rabbit arterial smooth muscle cells (ASMCs) and to explore the possible mechanism. Methods Rabbit model of chronic renal failure was established by the ligation of renal arterial branches. ASMCs were incubated in the media with various concentrations of chronic renal failure serum cultured in vitro. Cell proliferation was assessed by MTT. Cell apoptosis was detected by Hoechst33342 staining. NF-κB p65 nuclear translocation was analyzed by immunofluorescence. Expression of proliferating cell nuclear antigen (PCNA) and NF-κB p65 proteins in response to chronic renal failure serum in ASMCs was determined by Western blotting. Results Lower concentrations of chronic renal failure serum (≤ 10%) could significantly promot the proliferation of ASMCs in a dose- and time-dependent manner. Higher concentrations of chronic renal failure serum (＞10%) could significantly inhibit the proliferation and induce apoptosis of ASMCs compared to the normal control (P＜0.05). Under the stimulation of lower concentrations of chronic renal failure serum, the expression of PCNA and NF-κB p65 increased significantly compared to the normal control (P＜0.01), while decreased markedly under the stimulation of higher concentrations of chronic renal failure serum compared to the normal control (P＜0.01). Under the stimulation of 10% chronic renal failure serum, nuclear translocation of NF-κB p65 in ASMCs was found. Conclusions Different concentrations of chronic renal failure rabbit serum can effectively induce ASMCs proliferation or apoptosis. The mechanism of promoting proliferation may be mediated by activating NF-κB, which will be useful for the treatment of accelerated atherosclerosis in chronic renal failure.

Background Compare with the lamellar laser refractive surgery,the laser slip on the surface operation is a better method in the correct of refractive error without the flap-related complications.However,whether to remain corneal epithelial flap and its influence for epithelial healing and visual restoration are still under investigation.Objective The aim of this study was to compare the short-term clinical efficacy of epipolis laser insitu keratomileusis (Epi-LASIK) and flap-free Epi-LASIK for correction of refractive error in high myopia.Methods The paired control design was adopted.Sixty eyes of consecutive 30 patients with high myopia were collected in this study.The written consent form was obtained from each patients prior to operation.Regular EpiLASIK was performed in the right eyes and the flap-free Epi-LASIK was carried out in the left eyes.Patients were followed-up for one month.The postoperative ocular irritation symptoms were scored,and the healing period of corneal epithelium and uncorrected visual acuity were examined at 1,3 and 5 days after operation.The naked visual acuity,diopter,best corrected visual acuity and the grading of haze were recorded and compared between the two groups at one month after operation.Results After surgery,the scores of corneal irritation were 3.13 ±0.43 and 3.30±0.47on the first day,showing insignificant differences between these two groups (t =- 1.54,P＞0.05 ).However,there existed statistically significant difference in the scores of corneal irritation on the third day after operation between the two groups (t =- 17.95,P＜0.01 ).The average time of corneal epithelial healing were (2.58 ±0.49 ) days in the flapfree Epi-LASIK group and ( 3.98 ±0.74) days in Epi-LASIK group with the significant difference between them (t=-11.36,P＜0.01 ).There was no statistical difference in uncorrected visual acuity in the first day (0.59±0.12 vs 0.58±0.11,t=0.39,P＞0.05),the fifth day (0.69±0.08 vs 0.67±0.09,t=0.84,P＞0.05) and 1 month (t =-1.90,P＞0.05 ).No significant difference was seen in the diopter between the two groups in 1 month after surgery (-1.03±0.45 vs -1.07 ±0.38,t =-0.31,P＞0.05 ).The eye numbers of corneal haze for 0 grade were 27 ( 90.00％ ) and over the 0.5 grade were 3 ( 10.00％ ) in flap-free Epi-LASIK group respectively,and those of corneal haze for 0 grade were 26(86.66％ ) and above the 0.5 grade were 4 (13.33％) in Epi-LASIK group respectively,showing a considerably difference between the two groups (x2 =0.0031,P＞0.05).Conclusions Both the flapfree or reserved epithelial Epi-LASIK allow the safe and effective correction of refractive error in high myopia,showing good predictability and stability in short term.Flap-free Epi-LASIK can relieve the corneal irritation symptom and accelerate the healing of corneal epithelium and recovery of visual acuity.

Objective To explore the correlation between the epicaridal adipose tissue (EAT)volume and the SNYTAX score in patients with coronary artery diseases and to evaluate its clinical value.Methods Epicardial fat volume of 102 patients with coronary heart disease in our hospital were measured on dual-source CT angiography images,SNYTAX scores were calculated,and level of blood lipids,blood glucose (Glu),blood pressure,renal functional parameters and body mass index(BMI)were collected.Depending on SNYTAX scores,patients were divided into three groups (mild 0-22,moderate 23-32 and severe>33).The difference of EAT volume between groups and correlation with other indicators were analyzed.With indictors statistical significant in one-factor analysis,multi-ple regression equation was constructed to evaluate the risk factors of coronary artery diseases,particularly correlation between EAT volume and SNYTAX score.Results EAT,TC,TG,HDL,HbALc,GLu and BMI were significant different between three groups. Pearson regression showed that EAT,TC,GLu and BMI were independently risk factor in relation to the value of SNYTAX.Among them,standardized regressive coefficient of the EAT volume was the highest (β=0.52).Conclusion EAT volume is significantly positively correlated with the SNYTAX score in coronary heart disease,which can be as an effective predictor for its severity and prognosis.

Objective To investigate the expression of SEL1L and p63 protein in esophageal squamous cell carcinoma and precarcinomacous lesion.Methods Immunohistochemical staining(EnVision method)was employed to detect the expression of SEL1L and p63 protein in 60 samples of esophageal squamous cell carcinoma,32 samples of high grade esophageal intraepithelial neoplasia,13 samples of low grade esophageal intraepithelial neoplasia and 33 samples of normal esophageal mucosa.Results The positive rate of SEL1L protein expression was 61.5%in low grade intraepithelia neoplasia,90.6%in high grade intraepithelial neoplasia and 96.7%in esophageal squamous cell carcinoma,significantly higher than that in normal esophageal mucosa(6.1%)(P0.05).Conclusion Both the expression of SEL1L and p63 protein increases steadily in the progression of esophageal squamous cell carcinoma,which indicates that the two genes may play a role and cooperate with each other in the carcinogenesis.

Objective To explore the therapeutic efficacy of irbesartan combined amlodipine for the treatment of hypertension and diabetic nephropathy.Methods 120 patients with diabetic nephropathy and hypertension received from March 2011 to March 2014 were randomly divided into three groups according to its administration circumstances ( irbesartan group and amlodipine group, irbesartan and amlodipine groups) , with 40 patients in each group.Blood pressure, 24h urine albumin, 24h urinary protein excretion and urine β2-microglobulin and other indicators of the three groups of patients were observed and compared after 10 weeks of treatment.Results After treatment, the total efficiency of A, B two groups was no significant difference.The total effective rate of group C (92.5%) was significantly higher than that in A group (χ2 =6.65, P<0.05), the total effective rate of group C was significantly higher than that of group B (χ2 =7.81, P<0.05).The blood pressure in patients of three groups were all dropped to normal after treatment, but the one in combination group was significantly lower than the irbesartan group and amlodipine group, the difference was statistically significant (P<0.05).The urine tests related indicators of patients in the three groups were also significantly reduced after treatment , but 24 h urine albumin, 24 h urinary protein excretion and urine β2-microglobulin in combination group were significantly lower than the irbesartan group and amlodipine group, the difference was statistically significant (P<0.05).Three groups were no obvious adverse reactions. Conclusion Irbesartan combined amlodipine for the treatment of hypertension and diabetic nephropathy has significant efficacy compared to single drug.
